Fig. 2

Real-time bedside monitoring system. Good signal quality can be verified via the real-time bedside monitoring system. Below the green heart in the top panel on the left, the maternal heart rate is depicted. Right next to this, the uterine activity is shown. Below the blue heart on the right side of the top panel, the fetal heart rate is depicted. The white lines represent the output from the six abdominal electrodes, while the green line is a computation of the fetal signal, after subtraction of the maternal signal. In the lower panel in the middle, an estimate of the signal quality is shown. The user interface can be switched to a different screen in which the cardiotocogram is depicted
